What are these called

[Wereongunoil]

In my world they're called scent cases but there must be another name for them.

Does anyone have any idea of what they are

Do they go in the toilet?

No, they're tiny.

I think I've found them called biopsy cassettes

It seems you can buy 1500 for around £350

I only want 10 🤣

What do they do?

Last time I saw anything like that, I was working in a post office and someone was sending live bees 😲

Air freshener?

I've no idea what their intended use is but I want them for hiding tiny bits of scented cloth so that the dogs searching for said bit of cloth can't interfere with it

Yes, biopsy cassettes. You might be able to get them in smaller units on Ebay.

Buy some cheap plastic eggs off eBay they have small holes which you could make bigger if you needed too
about £5 for 12
